ROAD DRAG.

Application led June 15, 1922.

To all whom t may concern:

Be it known that I, GEORGE H. GUNDER- son, a citizen of the United States, residing at Potter, in the county of Cheyenne and State of Nebraska, have linvented a new and useful Road Drag, of `which the following is a specification.

`This invention relates to road drags, and has for its object the provision of a device which will move the dirt from the sides of the road to the center with the scraping blades arranged successively and at such an angle that the rear blades will cover substantially the same width of roadbed as the front blades, and whereby the drag will ride over ditches without upsetting.

The invention further contemplates the luse'of adjustable and reversible blades secured yto the body of the drag with the body being constructed of such material that the drag will not bounce over the roadbed when it meets with obstructions.

`The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawing, but `may be changed and modified so long as such changes'and modifications mark no material departure from the salient features of the invention as eX- pressed in the appended claims.

` In t-he drawing F ig. l is a view in perspective of the road drag when being drawn over fiat surfaces.

Fig. 2 is a bottom plan view of the road drag adjusted for treating crowned roadbeds. Y

Fig. 8 is a vertical section taken along the line 3- 3 of Fig. 2.

Fig. 4 is a vertical section taken along the line 4 4 of Fig. 2.

The road drag,` generally, comprises a pair of sections linked together with their rear adjacent portions adapted tobe adjustably spaced wherebythe road drag may be used for honing land for irrigation purposes,- or `for roadbeds, and yet may be equally well used for smoothing crowned roadbeds, the depthof the drag being such, as compared `toits width, that the .drag will-not ordinarily tilt when vbeing drawn over ditches. 1 Referring tothe drawing, l, 2 and 3 des? Serial No. 568,553.

ignate transverse parallel frame bars having theil` ends located in staggered relation so that said ends will be offset relative to a line running centrally and longitudinally of the roadbed.` A plurality of bars 4 and 5, having their ends in abutting relation between pairs of the frame bars and located at right angles to said bars, space the frame bars from each other. The spacing bars 4 are secured at their opposite ends, respective- 1y, to the frame bars l and 2, while the spacing bars 5 have their ends secured, respectively, to the bars 2 and 3. The two of the spacing bars 4 abutting one face of the cen tral portion of the frame bars 2 are in alinement with the two spacing bars 5 abutting the opposite face of the central portion of the bar 2. y

Diagonally disposed bracing bars 6 abut faces of the frame bars 2 and 3 at one end and have their other ends beveled and se-- cured, respectively, to the spacing bars 4 and 5, upon the outer side of a section of the drag, while brace hars 6a are similarly employed on the inner side of each section. These bracing bars are arranged at an acute angle to the frame bars 2 and 3, and form substantially the outer and inner sides of each section of the road drag.

Running substantially centrally of each section and through perforations in the frame bars l, 2 and 3, is a tie rod 7 firmly binding the three frame bars securely against the abutting ends of the spacing bars 4 and 5. Shorterv tie rods 8, respectively bind pairs of the frame bars together, such as l, 2, and 2, 3, respectively. Running diagonally of the frame bars and through perforations in said bars and through perforations of certa-in of the spacing bars 4 and 5, are tie Vrods 9 substantially parallel to the alined brace bars 6 and 6. These tie rods further aid 1n reinforcing and securing the frame bars in position relative to the spacing bars.

The tie rods 7, 8, 9. are arranged in different horizontal. planes and cross each other.

Secured upon the underside of the frame bars l.` 2 and 3 are wear plates l0. These plates have countersunk perforations in which are seated the heads of bolts ll passing vertically through the frame bars and locked against removal by `nuts on the threaded ends of thebolts. These bolts securely fasten the wear plates to the frame bars.

lll)

Mounted upon the lower portions et the forward faces ot the respectiveraine 'bars 1, 2 and 3, are scraper blades 12 rigidly secured to the frame bars by means o1 bolts These blades are reversible and adjustable for wear. By means ot' the additional pertorations 14 spaced above the perforations for the normal passage of the bolt 13, the

blades may be lowered when their scraping edgeshave been sufficiently worn.

The centrally disposed tie rod 9 of each section is provided with an eye 15 which provides means 'for securing the usual drag chains to the drag. .Y j

Upon the forward faces of the trame bars 1, and on the ends of the bars which are adjacent to each other are rigidly" secured metal hinge plates 1G and 17. The plate 16 is provided with a hook 18 adapted to 'en. gage an eye 19 on the end ol? the plate 17 for piv'otally connecting the adjacent ends 'of theftrame bars 1 together.

0nthe outer 'faces of the rear frame bars 31 ajresecured metal plates 2O having hooks 21adapted toreceive links of the chain 22, whereby the rear inner ends 'of the sections maybe variously spacedV from each other, depending upon the length or' the chainY 22 engaged by the hooks 21. By employing` such means for adjustably spacing the rear ends et the sections from each other, the road drag is adapted toeifectively hone crowned roadbeds,` the spacing ot' the rear adjacent. ends of' the sections depending upon the depth of the crown of the roadbed.

By providing the sections with a greater length than width and. employing'more than two blades, the road drag may be drawn over ditches without any possibility of upsetting the drag, and by the` use of wood in the construction of the sections, the drag will not bounce over the roadbed when it meets with an obstruction.

By making the blades 12 reversible and adjustable, it will not be necessary to discard the blades when they have been wormV to some extent. Y

The staggeringof the ends of the frame bars 1, 2 and 3, provides for a diagonal disposition of the spacing bars 4 and 5, with respectv to the roadbed, whereby the drag will be pulled at substantially an angle or 't5 'degrees toa line running ongitudinally et the center ot the roadbed Thus. the dirt will be drawn troni the edges oithe roadbed towards the center and lill in the hollow places.

The angular disposition ol the members comprising the sections of the road drag causes the-rear scraper blades to cover substantially the saine width of the roadbed as the front blades. Y Y
